Thanks for info, yes batteries have approx. 28v at the charge point. I was resetting the datum when the fault occurred, switching on and off will not clear the fault, I will recheck the batteries off charge but I’m fairly sure they are ok. (2 mths old – but did get discharged, hence resetting the datum).
How do you clear a fault? Or is the pcb/processor passing a small current through the brake coil and detecting an open circuit?
Then most likely as suggested you have knocked the dip switch for the hand of the lift, it is right at the side of the program dip switch
